Inventor: VAN DER LINDE ROBERT
IPC: C08L63/00
Filed: 1986-12-05
Granted: 1991-06-18
Abstract: ABSTRACT          The invention relates to a resin composition, comprising a mixture of at least two resins A and 8, wherein resin A the reaction product of an epoxidized fatty acid ester of a polyvalent alcohol with a carboxylic acid is and resin B a carboxylic acid-modified ester of a polyvalent alcohol is. The resin composition is obtainable by mixing the resins A and a during such a time and at such a temperature that a partial pre-reaction takes place.         The resin composition can be applied in the production of surface-covering layers especially in the production of linoleum.

Title: Handling of sheet materials
Inventor: FREEMAN MICHAEL A
IPC: B65H29/64
Filed: 1987-03-16
Granted: 1991-04-02
Abstract: ABSTRACT            Improvements Relating to the Handling of Sheet Materials.          The invention provides that a vacuum drum with rows of vacuum ports over its surface is used to transport self adhesive labels from a first location at which the labels are applied (adhesive surface outwards) to the drum to a second location at which the labels are detached from the drum.  The labels are held to the drum during the transport by applying vacuum to the ports until the label reaches the second location, when the first and second rows of ports at the leading edge of the label are applied with air under pressure, the pressure of the air supplied to the second row of ports being less than that supplied to the first row and slightly in advance in the time sequence, so that the edge of the label is slightly inwardly of the adjacent label extremity, initially lifted from the drum and then said extremity is blown sharply away from the drum providing effective, positive and reliable detachment of the labels from the drum.

Patent CA-1331096-C (CA)
Inventor: LUMMER RICHARD
IPC: B22F1/145
Filed: 1988-06-17
Granted: 1994-08-02
Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method for the annealing of iron powder which has been generated by compressed-gas atomization or pressurized-water atomization of an iron melt. Particles of such iron powder are surrounded by an iron oxide film. The iron metal powder particles are reduced in a reducing atmos-phere at a temperature from 900 to 1200°C.  A reducing atmosphere is maintained by continuous feeding of hydrogen in the atmosphere containing water vapor.  The known annealing method for iron powder is improved by reducing the use of hydrogen as a pure gas and gaseous or liquid hydrocarbon compound are added during the annealing process in an amount which is below the amount at which soot formation commences.  A preferred hydrocarbon composition is natural gas.

Title: Thermal crown controlled rolls
Inventor: EIBE WERNER W
IPC: B21B27/06
Filed: 1988-11-28
Granted: 1993-01-12
Abstract: THERMAL CROWN CONTROLLED ROLLS                 ABSTRACT OF THE DISCLOSURE Rolling mill work and back-up rolls comprising an arbor with a sleeve shrunk thereon have circumferential grooves  formed in the external  surface of the arbor, through which heating or cooling liquid is supplied from external sources so as to expand or contract the sleeve and change the roll crown and contour.   The fins,  or material   between   grooves,   may   have   higher   heat conductivity than the material of the arbor and sleeve, and are proportioned to transmit rolling forces without reducing roll stiffness.  A liquid supply system provides liquids of different temperatures to selected sections of the grooves along the roll working surface; and strip of different widths but of uniform gauge across the strip is rolled by suitably adjusting the temperatures of the hot and cold liquids so supplied.

Filed: 1989-03-17
Granted: 1993-10-19
Abstract: ABSTRACT OF THE DISCLOSURE    A data processing system handles memory management exceptions caused by a faulting vector instruction in a vector processor by halting the execution of the faulting vector in-struction being executed when the exception occurred and by setting the state information for the vector processor to acknowledge the presence of the exception and to include informa-tion about the suboperation of the vector instruction being exe-cuted when the exception occurred.  The scalar processor is not interrupted at this time, however.  Any other vector instructions executing simultaneously with the faulting vector instruction are allowed to continue so long as those instructions do not require data from the faulting instruction.  The faulting partially com-pleted vector instruction resumes execution after the operating system has processed the memory management exception.

Granted: 1994-08-16
Abstract: GASKET COMPRESSION CONTROL HAVING     TENSION-RELATED FEEDBACK                ABSTRACT OF THE INVENTION     When tensioning a gasketed joint, the drive system applies rotational force to a threaded fastener while the monitor and control unit continuously compares a torque-related variable to a shutoff point.  When the shutoff point is reached the control system reduces the drive system power, preferably to zero.  After a preselected time pause the drive system is re-energized and applies another torque application until the torque-related variable again reaches the shutoff point.  When the gasket is adequately compressed so that further torque applications cause insignificant increases in gasket compression, the tensioning operation is terminated.  Feedback is provided by tension-related variables such as incremental angle of turn and/or incremental elapse time of the torque application to determine when the tensioning cycle is complete.

Title: Separation of gaseous mixtures
Inventor: GARRETT MICHAEL E
IPC: B01D53/04
Filed: 1989-05-23
Granted: 1993-07-13
Abstract: ABSTRACT                 SEPARATION OF GASEOUS MIXTURES     A method and apparatus is disclosed in the separation of a gaseous mixture by pressure swing adsorption utilizing two beds of adsorptive material which are operated out of phase in the cycle  thereby  providing  a  more-or-less  continuous  flow  of product.  Each adsorbent bed contains a heat exchange chamber holding a volatile liquid.   The liquid gives up vapor in the bed undergoing adsorption and condenses in the bed undergoing desorption.  Heat is thereby transferred between the beds, thus improving the efficiency of each stage by retaining heat which would otherwise be lost.
